Nausea and vomiting when the house is hot is considered chronic superficial gastritis, which is more common in gastroenterology. The onset of the disease is related to the patient’s cold stomach and irregular diet, with excessive secretion of gastric acid, which manifests as discomfort such as loss of appetite and nausea and vomiting. The symptoms are aggravated when the temperature in the room rises. You can go to the hospital for gastroscopy and apply omeprazole enteric capsules and magnesium aluminum carbonate chewable tablets for symptomatic treatment under the guidance of the doctor after diagnosis, and do not eat raw and cold food in the diet.
